His eye contact sounds fine. At his age it's completely normal for him to be more interested in his toy than you. As long as he looks at you when you talk to him 90% of the time he's fine. The bad eye contact we're talking about is more like when they look around you or through you. My son looks next to me when I'm talking to him or he looks up. He also gets engrossed in his toys and things too but the difference is when I finally get his attention he still won't look at me. I really think your son is completely typical. Don't worry about the babbling. Like a PP said, if he's still not babbling by 12 months then worry. In the meantime enjoy the relative peace and quiet.
